Complex plotting in R
Hi list,
I'm looking for a function or a combination of functions to do panel plotting of mixed graph types with the same x axis.
I would like to construct a panel with 3 stacked windows with on top a histogram, below that 2 cdf plots. They all have the same x axis value but different y axis values. Is it possible to construct something like that?
I've looked into the lattice package

assign() problem
I've written a piece of code (see below) to do a wavelet image
decomposition, during the evaluation of this code I would like to write
the results of some calculations back to the R root directory. I used
assign() to do so because the names should vary when going thrue a
while() loop. For some unknown reason I get an error that says:
Error in assign(varname[i], imwrImage) :

Cross correlation in time series
Hi list,
I'm working on time series of (bio)physical data explaining (or not) the
net ecosystem exchange of a system (+_ CO2 in versus CO2 out balance).
I decomposed the time series of the various explaining variable
according to scale (wavelet decomposition). With the coefficients I got
from the wavelet decomposition I applied a (multiple) regression, giving
some expected results. The net

Beginners question
Dear list,
I've been messing around with coding functions in R and it just won't make
sense to me.
Running my analysis by hand on command line is fine and works but because
of the repetitive nature of the job I would like to code a function for it.
My problem:
I would like to read in data from a file in my current working dir.
so my code would look like:

Iterative Proportional Fitting, use
Hi list,
I would like to normalize a matrix (two actually for comparison) using
iterative proportional fitting.
Using ipf() would be the easiest way to do this, however I can't get my
head around the use of the function. More specifically, the margins
settings...
for a matrix:
mat <- matrix(c(65,4,22,24,6,81,5,8,0,11,85,19,4,7,3,90),4,4)

wavethresh: length must be power of two
Hello.
I am using the 4.2 version of the wavethresh package available from here: http://www.stats.bris.ac.uk/~wavethresh/ trying to follow the book of Nason (http://www.springer.com/978-0-387-75960-9).
I am interested in the analysis of several years time series of daily data with wavelets methods. But the functions of this package only accept data whose lengths are power of two, even for

spatial statistics on images, any packages?
Hi list,
Is there a package that covers the evaluation of spatial statistics on
images and not on point data? I've converted an image matrix to x, y
coordinates and a measurement value but evaluation with the package
spdep (not really designed for image data I suppose) is unworkable. Any
suggestions?

non-linear curve fitting
Hi list,
I have a little curve fitting problem.
I would like to fit a sigmoid curve to my data using the following equation:
f(x) = 1/(1 + exp(-(x-c)*b)) (or any other form for that matter)
Where x is the distance/location within the dataframe, c is the shift of the curve across the dataframe and b is the steepness of the curve.
I've been playing with glm() and glm.fit() but without

waveThresh plot axis
Dear,
I am using WaveTresh for Haar Wavelets. It works all fine exept when I
want to adjust the axis on the wavelet coefficient plot:
input: wlh_ponds<-wd(input_waves[,1], family="DaubExPhase",filter.number=1)
plot: plot(wlh_ponds,scaling="by.level")
My problem is twofold=
-I want the original x-axis of the data on that plot, not 1/2 of the
axis. This would make

Samba-Cups: all works except browsing when printer is not defined in smb.conf
Cups 1.2.7
Debian Etch with Samba 3.0.24
Clients: WinXP SP3 (with Firewall completely off for testing)
When I define a printer specifically in smb.conf, they show up as shared
printers in WinXP. But when I follow the normal way (see below) to load all
from cups they don't.
I followed mainly the latest SAMBA-HOWTO (chapter 21-22)

Wavethresh - Scaling - Wavelet
Hi users,
When I use the scaling = by.level, appear in the R, values of the scales by
level, but I'm viewing the levels 10, 11, 12, 13 and 14. I do like to have a
global scale, using the value of Level 14 ".
I would like to see everyone on the same scale level of 14. If I leave the
scaling = global, it takes the value of level 10.
How i do it?

[LLVMdev] Using LLVM as a crosscompiler
Hi Koen,
The process to build llvm-gcc as a crosscompiler is basically the same
as build a normal gcc as crosscompiler. The differences: you need a
LLVM installed (compiled for the host). You must configure llvm-gcc
with --enable-llvm.
Problems:
- Today LLVM supports ARM/EABI, but llvm-gcc don't. You must apply the patch:

Samba password problem when in domain
Hi,
In our network, I have set up a samba server in a workgroup. We're now migrating
to a domain, using SBS 2003. When I locally login on XP and access the samba
server, it works just fine. But, when I login on the domain and then try to
access the same samba box, it doesn't accept my password.
The username for my samba account and account on the domain are the same. Also,

SAMBA digest 1647
Very very very cool. I have been thinking of this one myself. I
thought I tested it and that I came to the conclusion that Samba did
not recognize named pipes, and just treated them like normal files
(overwriting them when you drag a text file onto them). But I must
have made a mistake somewhere. It' perfect.
The way I will set it up is like this: a Progress program will sit on

Alleged bug in Silk codec
Yes, regarding the unsigned to signed conversion you are right, it is implementation defined. I just had an issue a couple of years ago with a compiler which incorrectly treated unsigned overflow as undefined rather than implementation defined?
Regarding the 64 bit profiling: I looked at the disassembly (gcc ?c ?S ?O2 ../opus/silk/sum_sqr_shift.c ?I../opus/include ?I../opus/celt) of the 64 bit
